Four 1 hour interviews. I was asked basic and technical questions, also free lunch. The technical questions were in many cases very vague and they would not elaborate making it difficult to give them an answer they seemed to want. They would just keep repeating the question.
They contacted me for an in person interview and then asked me leet code style questions. After the interview I heard back from a recruiter who set up another phone call with me
I interviewed at Northrop Grumman (Huntsville Park, AL)
Interview
Technical questions and behavioral questions (STAR formatting) with the normal what draws you to work for us. Microsoft Teams meeting with a panel to review answers. Took roughly 1 hour and it was a very straightforward and easily made process.
Formal, not too stressful. Ensures you understand the basics and thay you know what you're talking about as you may be getting interviewed by somebody that's technical at some point.
